Raining Sockets is a high-performance, non-blocking, sockets-based framework. Non-blocking IO (NIO or NBIO) allows one to create thousands of connections in a single thread, thus making applications highly scalable, compared to the thread-per-client model used prior to JDK 1.4. A user only needs to override the event that needs to be customized, such as what to do with arrived (or arriving) data, or what to do when a write has completed. Raining Sockets has been tested successfully with over 13,000 concurrent connections.
Re: Someone forgot to link the screenshot ...
I just checked, and the page does show scr3.png. Both on top and in the screenshots section. Could you elaborate.
